高功率密度通用型3相PWM控制器

RT8800A是一通用型多相同步降压转换器，适合高功率密度应用，可在自动的错相设定中执行2或3同步降压转换阶段。此多相架构让供电应用在高输出电流中，可维持低功耗和输入、输出电容的低应力。输出电压透过PI接脚的外部参考电压精确调节，当配合DAC发生器RT9401A/B，即可提供Intel^® VRD10.x 或AMD^® K8标准输出电压。RT8800A采用创新的时分 DCR 电流检测技术实施电流平衡操作、降压调整和过流保护，并用检测电流的通用GM放大器消除偏移误差及GM间的线性不一致性。由于现代的主板普遍使用了低于毫奥姆级的电感，小的偏移和线性不一致性即 •5V 供电\n•以外部参考电压调节的输出电压\n•使用 DCR 电流检测技术进行功率级热平衡\n•内部软启动\n•过压保护\n•电源良好指示\n•符合 RoHS 规范且完全无铅;
